In an exam room, Luka examines Kate. Her fever has gone up since the last time Carol took her temperature. Carol makes a comment about how long it takes to get out of the house with the twins, and she jiggles Tess comfortingly and says she knows Luka and Haleh "think I'm being crazy, right?" Luka tells her it's good that she brought Kate in; it's probably nothing, but a fever in a four-week-old "can be cause for concern." Carol agrees, adding that she knows all the things that can go wrong. Luka offers to do a septic work-up. Carol asks if that's necessary, and Luka tells her she has to decide. Carol says that as a nurse, she would say no, and looks to Haleh for back-up. "And as a mother?" Luka prompts her. Carol says she just wants to make sure Kate is okay. Yes, yes, yes, professional-maternal conflict -- we get it, for god's sake. Luka says he can do a less invasive test and take it from there when they get the results; Carol wants Haleh to draw the blood because she's "the best stick in the ER." I really and truly could not care much less about this sanctimoniously trite subplot.
Cleo asks Chad, "How are you feeling?" Chad asks if his mom has arrived. "Not yet," Cleo tells him, and asks if his father's around. Chad says while laughing bitterly that he saw his father yesterday, in a Christmas photo of his father and his father's new family "vacationing in Florida." Cleo says she'd like to call and let his father know "what's going on with" Chad, but Chad immediately snaps, "He doesn't care," adding unconvincingly that he and his mother "are better off without him anyways." Cleo regards him silently. He asks when he can go home, and Cleo says she's still waiting on some tests, and Chad grumbles, "Come on -- it's Christmas." Lily opens the door and tells Cleo that Chad's mom has shown up. Out in the hall, Cleo finds Chad's Mom holding an unlit cigarette and fidgeting. CM asks after Chad, and Cleo tells CM that Chad has a broken ankle, but they still have to wait for the results of the CT to rule out a head trauma. CM says she doesn't know how it happened, and Cleo asks, "You were home?" CM says she had people over for "a small holiday party," and when Cleo asks if CM even heard Chad fall, CM dissembles: "There was music playing, people talking . . ." Cleo sighs and tells CM that Chad's blood-alcohol level is point-two-six, and she asks CM if she knew Chad was drinking. CM starts to lie, then admits that she let him have a beer: "It's Christmas Eve, he's on vacation." Cleo says sternly, "He's had more than one beer." CM says brightly that maybe Chad took something from the bar and she didn't notice. Cleo folds her arms, and CM goes on the defensive, whispering, "Oh, I get it, you think this is my fault," and Cleo says she isn't trying to place blame, but CM interrupts her: "No, you're right -- I should have known what was going on. I mean, what kind of a mother am I?" Before CM starts crying, Cleo suggests that CM go see Chad, which she does. Cleo stays at the door, watching as CM kisses Chad's forehead.
